1. A method of moving containers having a collar along a moving path comprising the steps of:
(A) providing a guiding system, said guiding system comprising:
a first guide profile having an upper support face adapted for supporting at least a first portion of the collar of containers, and a lateral guiding edge adapted for guiding at least a first portion of a lateral face of the containers;a second guide profile having an upper support face adapted for supporting at least a second portion of the collar of containers, said second portion being different from said first portion of the collar of the containers, and a lateral guiding edge adapted for guiding at least a second portion of a lateral face of the containers different from said first portion of the lateral face; wherein said first lateral edge is located in front of said second lateral guiding edge, but is distant from said second lateral edge so as to define there between the moving path for at least a portion of the containers, and
a means for reducing the friction at least the collar of the containers at least on the said upper faces of the said first and second guiding profiles, when said containers are moving along the path, wherein said means for reducing the friction of the collar of the containers at least on the said upper faces of the said first and second guiding profiles comprises:
a first dispensing channel associated to the first guide profile, said first dispensing channel having (a) an inlet adapted to be connected to a lubricant dispensing system adapted for dispensing lubricant under pressure into the said first dispensing channel, and (b) an outlet with an outlet opening with an equivalent diameter comprised between 0.3 and 7 mm directed towards the upper support face of the first guide profile in the vicinity of the lateral guiding edge, wherein said outlet opening is associated to a first groove formed along the upper support face of the first guide profile, said first groove having:
a length path greater than the equivalent diameter of the said outlet opening comprised between 1 and 20 times the equivalent diameter of the said outlet opening, anda maximum width,wherein said groove extends in a portion of the upper face of the first guide profile adapted to contact the first portion of the collar of the containers; anda second dispensing channel associated to the second guide profile, said second dispensing channel having (a) an inlet adapted to be connected to a lubricant dispensing system adapted for dispensing lubricant under pressure into the said second dispensing channel, and (b) an outlet with an outlet opening with an equivalent diameter comprised between 0.3 and 7 mm directed towards the upper support face of the second guide profile in the vicinity of the lateral guiding edge, wherein said outlet opening is associated to a second groove formed along the upper support face of the second guide profile, said second groove having:
a length path greater than the equivalent diameter of the said outlet opening comprised between 1 and 20 times the equivalent diameter of the said outlet opening, anda maximum width, wherein said groove extends in a portion of the upper face of the second guide profile adapted to contact the second portion of the collar of the containers; (B) applying a pneumatic force on said containers; (C) moving said containers the one after the other along the said moving path according to a forward moving direction; and (D) intermittently pushing a quantity of lubricant through the outlet opening of the first dispensing channel and of the second dispensing channel respectively into the considered first groove and into the considered second groove. |
